“Regression analysis on environmental factors affecting crop yield in Maji Ndogo # 🌾 Predicting Crop Yields in Maji Ndogo: A Linear Regression Learning Journey This repository contains the code, data, and visuals used in the **Maji Ndogo Crop Yield Analysis** project — a data science exploration of how environmental factors such as temperature and pollution influence agricultural productivity. What began as an ALX classroom assignment evolved into a personal project to strengthen my data analysis and storytelling skills. I refined the original notebook, explored the data more deeply, and transformed it into a portfolio piece that showcases both technical understanding and interpretation. --- ## 📊 Project Overview **Goal:** To determine whether temperature or pollution levels have a measurable linear relationship with standardized crop yield in Maji Ndogo. **Key Findings:** - 🌡️ **Average Temperature:** Showed almost no linear relationship with yield. - 🏭 **Pollution Level:** Displayed a weak negative correlation — higher pollution slightly reduced yield. - 📈 **Model Evaluation:** Low R² (~0.08) suggests pollution alone cannot explain yield variations. - 🔍 **Residual Analysis:** Residuals were mostly random, but minor heteroscedasticity hints at missing variables. 📖 **Read the full article on Medium:** 👉 Predicting Crop Yields in Maji Ndogo: A Linear Regression Learning Journey --- ## 🧩 Repository Structure Maji-Ndogo-Regression-Analysis/ │ ├── data/ │ └── maji_ndogo.db # SQLite database │ ├── notebooks/ │ └── Maji_Ndogo_Regression_Analysis.ipynb │ ├── visuals/ │ ├── temperature_vs_yield.png │ ├── pollution_vs_yield.png │ ├── residual_histogram.png │ └── residuals_vs_predicted.png │ ├── requirements.txt └── README.md --- ## 🚀 How to Run 1. **Clone this repository** ```bash git clone github.com cd Maji-Ndogo-Regression-Analysis Install dependencies pip install -r requirements.txt Launch the notebook jupyter notebook notebooks/Maji_Ndogo_Regression_Analysis.ipynb (Optiona …
